It's Fun to Play the Piano ... Please Pass It On!

I have been doing some modeling of actions with wood, but found that most of what i am doing is too complicated. What are some of the simplist actions you know of. Alsp, what is the difference between a fixed backchech and a backcheck connected to the hammer?

Tec,This toy piano has a rudimentary action in it. You may want to take some ideas from this design. The photos of the parts should be self-explanatory, but if not, let me know and I'll post a video of it in operation.

Probably after that comes something like the Zumpe action, where a fixed stick pushes against something like a knuckle, and just slides out from under when it is raised high enough. That would be like the action on a Rhodes.
